There's not much to add review wise. I agree with pretty much everything that has been said. Go through the queue once for the experience and then single rider thereafter. Since the vehicles hold four people, there will be plenty of single seats open to be filled.
Also, props to the lighting effects on the "tubes" running through the queue. The blue/black/white lights are very striking (hehe).
Also also, don't let the pre-show with Igor showing the ride vehicle mechanics frighten you. I don't think the ride ever gets to the level of spinning that his demonstration shows.
